Description

Technical Field

[0001] The utility model relates to an auxiliary device for a marine vessel replenishment device, in particular to a height indicating device for a marine liquid cargo replenishment pipeline. Background Art

[0002] At present, the devices for replenishing ships at sea mainly include the following forms:

[0003] Cable-type boom device: The early transverse liquid cargo supply device was installed on the boom, which was tilted out of the ship's side. Multiple guy ropes were used to tie the liquid infusion hose to make it suspended in the air, and a pulley was used to fix the hose joint to the receiving station. Although this method achieved the basic docking of the hose, it was complicated to operate and had poor stability in high sea conditions.

[0004] Constant tension overhead cable supply device: mainly used for large supply ships to accompany supply at sea. The device uses a constant tension overhead cableway to connect the supply ship and the receiving ship, and uses oars and steering devices to keep the two ships at a safe distance and the same speed. The oil hose slides from the supply ship to the receiving ship along the cableway by its own weight or under the traction of a traction device. This device has a complex structure but good stability and is suitable for large-scale supply operations.

[0005] Existing offshore oil pipeline supply devices have made certain progress in technology, but there are still shortcomings such as complex operation, poor stability, and difficulty in adapting to severe sea conditions. In particular, for constant tension elevated cable supply devices, when supplying in severe weather or at night, observers cannot effectively observe the distance between the supply pipe and the sea surface, and timely control the distance between the supply ship and the receiving ship to control the safe distance between the supply pipe and the sea surface to ensure the safety of the supply pipe.

[0029] like Figure 1 The structural diagram shown.

[0030] During the process of replenishing water and fuel between the supply ship 1A and the receiving ship 2B, a load-bearing steel wire is built between the supply ship and the receiving ship, and a supply pipe is slid from the supply ship to the receiving ship along the steel wire through a traction rope for replenishment. The utility model as a whole is attached to the supply pipe, slides with the supply pipe, is placed between the two ships, and hangs down with the supply pipe. By observing the schematic of the utility model, the crew can keep the distance between the supply pipe and the sea surface at a safe distance, so that the supply pipe will not be too loose and touch the sea surface, which will affect the safety of the pipeline during the replenishment process. The invention value of the utility model can be better reflected in harsh environments.

[0031] Specifically, if Figure 2 As shown, the utility model includes a hanging ring 1, an unwinding swivel 2, a hanging rod 3, and a luminous indicating ball 4. The hanging ring 1 is penetrated with a plurality of luminous beads 11. The hanging rod 3 is vertically connected to the lower side of the hanging ring 1 through the unwinding swivel 2. The luminous indicating ball 4 is hung at the lower end of the hanging rod 3.

[0032] The unwinding swivel 2 is used to prevent the suspension rod 3 and the luminous position indicating ball 4 from rotating and causing the hanging ring 1 to break.

[0033] After the hanging ring 1 is threaded with the luminous beads 11, it is completely sleeved on the supply pipe. The luminous beads 11 are in sliding contact with the surface of the supply pipe. The number of luminous beads 11 must be sufficient to avoid contact between the hanging ring 1 and the supply pipe, thereby ensuring the safety of the supply pipe. The luminous beads 11 can be fully threaded on the hanging ring 1.

[0034] The luminous indicating ball 4 is vertically arranged below the whole body for sea surface contact indication, so that by observing the fluorescence of the luminous indicating ball 4, it is confirmed whether it is under the sea surface. Of course, the gravity of the luminous indicating ball needs to be set to be greater than its buoyancy in sea water.

[0035] In this embodiment, the unwinding swivel 2 is an 8-shaped swivel, the upper first movable lifting ring 211 is connected to the hanging ring 1, and the lower second movable lifting ring 212 is connected to the first fixed lifting ring 31 provided on the top of the suspension rod 3.

[0036] like Figure 3 As shown, the hanging ring 1 is a steel wire rope with hanging holes 12 formed at both ends, and the hanging holes 12 at both ends are combined and hung together in the first movable hanging ring 21.

[0037] like Figure 4 As shown, a second fixed lifting ring 31 is provided at the lower end of the lifting rod 3 , and the luminous position indicating ball 4 is connected to the second fixed lifting ring 31 through a third movable lifting ring 32 .

[0038] In order to prevent accidents caused by slipping during installation, especially in an icy environment, an anti-skid sleeve 3a is fixedly mounted on the suspension rod 3. In another embodiment, anti-skid patterns are arranged on the surface of the suspension rod.

[0039] In this embodiment, the first movable lifting ring 211, the second movable lifting ring 212, and the third movable lifting ring 32 are all bow-shaped safety pin lifting rings, so as to facilitate the disassembly and assembly of the entirety of the utility model.

[0040] like Figure 2 As shown, Figure 5 , Figure 6 As shown, the unwinding swivel 2 includes a rotating body 221, a first T-shaped rotating column 222, and a second T-shaped rotating column 223. A first rotating hole 2211 is opened on one side of the rotating body 221. The first T-shaped rotating column 222 extends out from the first rotating hole 2211 from the inside to the outside. A first bearing 224 is arranged between the head end of the first T-shaped rotating column 222 and the inner wall of the first rotating hole 2211. The other side of the rotating body 221 is an opening for installing the first T-shaped rotating column 222 and the first bearing 224, and also for inserting the head end of the second T-shaped rotating column 223 and the second bearing 225. A nut 226 is connected to the opening. The nut 226 has a second rotating hole 2261 for the second T-shaped rotating column 223 to extend out. The second bearing 225 is arranged between the nut and the head end of the second T-shaped rotating column 223. The outer ends of the first T-shaped rotating column 222 and the second T-shaped rotating column 223 are both provided with through holes for connecting the bow-shaped safety pin hanging ring.

[0041] A more preferred embodiment is that a screw hole is opened on the outer wall of the rotating body 221 at a position between the first T-shaped rotating column 222 and the second T-shaped rotating column 223, and a bolt 2212 is arranged in the screw hole, and the inner body of the bolt 2212 is placed between the first T-shaped rotating column 222 and the second T-shaped rotating column 223 to limit the two to prevent the two from contacting and generating friction, or causing the bow-shaped safety pins arranged on the first T-shaped rotating column 222 and the second T-shaped rotating column 223 to contact and wear the end surface of the rotating body 221.

[0042] A more preferred embodiment is that a positioning bolt 2213 is provided on the side wall of the rotating body 221 on the periphery of the nut 226. By inserting the positioning bolt in the periphery, the nut 226 is positioned to prevent rotation, thereby preventing the nut 226 from accidentally detaching due to the rotation generated by the unwinding swivel 2 during operation. To facilitate installation, a locking hole 2262 is opened on the surface of the nut 226 for locking using a tool.

[0043] In this embodiment, the boom 3 is a hollow structure to reduce the overall weight and avoid excessive tension on the supply pipe under severe sea conditions.

[0044] In this embodiment, the length of the suspension rod is 50-120cm, preferably 80cm, the length of the hanging ring is 60-100cm, preferably 75cm, the height of the luminous indicating ball 4 is 8cm-12cm, preferably 10cm, and the width is 5-8cm, preferably 6cm.

[0045] In the above, the luminous beads 11 and the luminous indicating balls 4 are both solid structures, and the overall material contains fluorescent material, which can produce fluorescence when illuminated by a strong flashlight, making it convenient to use and observe.

[0046] When the utility model is in use, fluorescence is generated by irradiating the luminous beads 11 and the luminous indicating ball 4 with strong light, and the luminous beads 11 and the luminous indicating ball 4 are sleeved on the supply pipe and slide toward the receiving ship together with the supply pipe, and the device of the utility model is located in the middle of the supply pipe. By observing whether the luminous indicating ball 4 at the lower end is in contact with the sea surface, it is judged whether the supply pipe is at a safe height. The luminous beads 11 are used to indicate the position of the supply pipe. When the fluorescence is not bright enough during use, the luminous beads 11 and the luminous indicating ball 4 can also be irradiated with strong light by a strong flashlight to restore their fluorescent state for height indication.

[0047] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
